I am new to openfoam and am trying to follow the Chalmers "make a fish swim" case. I am getting errors when running it and don't really know what they are telling me (or how to interpret them). I see the Courant (CFL) conditions growing to 10^100, so I know that is a problem, but I don't necessarily know how to fix it. I know it usually is an issue based on either time step or resolution, but I imagine many people have successfully run this so I don't really know the problem. I know it used pimpleDyMFoam which is now just pimpleFoam, so not sure if that matters for getting errors? I am using openfoam8 on a mac, for reference.

The error is...

#2 ? in "/lib/x86_64-linux-gnu/"
